Louis M. Cotcliett, Brookline, Maas., assigner to fi Textile Patentv & Process' (Lo.` Incorporated,

` Boston, Mass., a

setta 'corporation' of Massaclni- Application october 15, 193i. serial No. sessel iz claims. l(ci. cimas) The present invention relates to textile apparay tus, and more particularly to improvements in machines for winding yarn from a bobbin on to a usable cone package. The present invention is particularly concerned lwith the prevention and elimination of loose, ilying lint which is a normal and usual accompaniment Yof this type ,of operation as the yarn is unwound and whipped from thevbobbin at winding speeds.

I am enabled to eliminate and control this normally loose, flying lint byl assembling the wound bobbin or bobbins in a compartment through which is maintained a constant draft of air of sufficient magnitude to :remove the lint to any suitable point. In a simple and practical embodiment of the invention I surround each wound bobbin with a cell which is in free com- 'munication at the lower portion with a conduit or air trunk through which is maintained a constant draft of air. The wound bobbin is supported upon a skewer in the cell, and the yarn is withdrawn from the upper portion, but due to 'the constantmaintenance of a down draft of air through the cell and about the bobhin, loose or free lint which results from the unwincling of the yarn from the loohbin ls withdrawn downwardly into the trunk, from whence it may be removed to a common collecting point. Each cell is so arranged in conjunction with the air trunk that during the winding operation the cell is in com munication with the trunk, but is readily shifted therefrom into a hobhin domng position to permit discharge of the empty or partially emptied loobbin on to a conveyor which removes it from the apparatus. v

In the accompanying drawings illustrating the preferred form of the invention, Fig. l represents a front elevation of a winding chine embodylng the :features of the invention; Fig. 2 is an elevation partially* in section illustrating the frame of the machine with the upper portion removed and showing more particularly the arrangement of the cells and lint-removing ducts; and Figs. 3 and e are details illustrating the n. ually operated mechanism for shifting the cells from winding to dong position, and vice versa.

The machine shown in the illustrated .embodiment of the invention comprises generally a frame l0, having a series of rotary guides l2 designed, in cooperation `with conical packages lll, to produce a familiar form of crossed wind. The winding mechanism may be conveniently driven in any suitable manner from an 'electric motor 16. The individual bobbins from which vthe yarn is withdrawn are indicated. at 18 as maintained in t cells`20, Each of these cells, as shown .more particularly in Fig. 2, comprises a cylinder open at top andbottom, and normally maintained in the vertical position shown at the right of Fig. 2. In this position the bobbin is supported from beneath by a sltewer 24, upon the end of an arm 26, which in turn is connected to the lower end of sliding rods 28, which are adapted to be manually depressed to depress the skewer through'an operating handle 30, as will be presently described. When the skewer is'depressed the bobbin is left supported upon a stationary ledge 32, and swinging movement of the cell into the inclined cloning position shown at the left of Fig. 2 permits the bobbin to be carried therewith and subsequently discharged upon the surface of a conveyor 34. This conveyor comprises an endless belt running lengthwise of the frame, and having cooperating inclined discharge surfaces 36 and 38, by which the empty or partially emptied bobbins are directed on to the conveyor. The conveyor passes at its opposite ends over pulleys 40 and 42, which may be driven by a chain 44 from a drive shaft 46 operated initially from the motor i6. With this construction bobbins discharged from the individual cells are removed to a common collection point in a manner which will be obvious.

During the winding operation the rapid whipping of the yarn from the surface of the bobbin package causes a substantial amount of free y. ing lint which may collect on the yarn or float freely in the air. I prevent this loose flying lint' by placing the lower end of each bobbin compartment in constant communication during the winding operation with a constant draft sufficient to produce a downward suction in the bobbin compartment. To this end Ifind it convenient to provide an airtrunk 5o, extending lengthwise of the frame at each side thereof, and' communieating with the open lower end of each-series oiV cells when located in winding position. As will loe apparent, each air trunk is of generally rec tear cross-section, encloses the bobloin supporting slrewer without interfering with the free movement thereof, and is in communication with the lower end ci `each enclosing cell 2c when the latter are positioned vertically. The two air trunks may each he contracted with an exhaust fan producing a suction within the trunk, or may he caused to merge into a single duct connected'with a similar fan for removal of loose lint downwardly through the trunks to a common collection point. Obviously, as the lint is free g and light, a slight draft is ple for the lil.
